There is a way to get health information that is the reverse of the typical search engine. You know how search engines work: enter keywords and you’ll get results from today going back in time. If you want to follow a topic going forward over time, you’ve got to return to the search engine and type in your request all over again.
The way I understand it, an alternative is Bloglines.
Bloglines will search into the future for you.
Bloglines Saved Search feature captures a requested search for you and then watches millions of active blog and RSS feeds for new references to that topic. Save your search once, and Bloglines will automatically watch the relevant activity for you. When something new pops up on the health topic you’re searching for, Bloglines grabs it and presents it to you on your My Feeds Page.
With Bloglines, is there any reason you couldn’t monitor emerging medical or technical developments?
